Step-by-step explanation:
The nurse should identify that the client might be experiencing infiltration as evidenced by the client's IV catheter site presentation.
Infiltration occurs when the IV fluid leaks into the surrounding tissue instead of going into the vein. This can cause symptoms such as pain, tautness, blanching, coolness, and edema at the catheter site. Infiltration should be addressed promptly by discontinuing the IV medication, removing the catheter, and notifying the healthcare provider.
